Offshore wind port

Port facility used to support construction and operation of an offshore wind project From Wikipedia, the free encyclopedia

An offshore wind port describes several distinct types of port facilities that are used to support manufacturing, construction and operation of an offshore wind power project. Offshore wind turbine components are larger than onshore wind components. Handling of such large components requires special equipment. Transporting of components between manufacturing and assembling facilities is to be minimized. As a result, a number of offshore wind port facilities have been built in areas with a high concentration of offshore wind developments.[1] For large offshore wind farm projects, some offshore wind ports have become strategic hubs of the industry's supply chain.[2]

Small oceanic ports

These are small port facilities to launch survey vessels used in an early stage of an offshore wind farm development.[6]

Manufacturing ports

Large offshore wind turbine components are difficult to transport over land. Locating a manufacturing facility at a port is more desirable. Subcomponents and materials may be brought through roads or railways. After components are built, they are typically shipped to a marshaling port for the final assembly.[6]

Marshaling ports

Marshaling ports (also known as staging ports[1]) are used to collect and store wind turbine components prior to loading them on to wind turbine installation vessels. They are preferably located where there is unrestricted air draft to the wind farm site.[6]

Operating and maintenance ports

Operating and maintenance ports house facilities and vessels that are required for ongoing operating and maintenance of offshore wind farms. This may include part warehouse, offices, and training facilities.[6]

Europe

The six leading offshore wind ports in Europe service wind farms in the North Sea. Their respective countries signed the Ejsberg Declaration in 2022 in which they agreed to coordinate supply chain activities to optimize the manufacture and delivery of wind turbine components.[7][8]

United States

As of 2021, offshore wind power in the United States was described as a "burgeoning" industry.[12] At that time, a number of ports were proposing to build or convert facilities to handle the large components needed to build potential offshore wind farms.[13][14][15] Among those on the East Coast, from north to south are:
